Acid Base Organic

Acid base organic chemistry reaction.
When does it occur?
What is the reaction between, please?
Thank you.

In the Level 2 organic standard the acid base reaction referred to is between amines (which are weak bases) and carboxylic acids (which are weak acids).

To help you understand this more here is a YouTube clip which takes you through the reaction (you don’t need to know this is a form of condensation reaction although it does make sense as condensation is water and water is a product of this reaction):

In reality you can just draw the salt formed and not need to name it.
Hope that helps you out JOLM
